Awesome, has it done much for your sound?

You needn't connect safety earth, it's optional. You must connect the ground of any upgraded RCA sockets to the CD player's ground of course, but that's stating the obvious!

Hi Simon

One of my DIY projects was a CD player based on a philips CDM12 and I used a wodden box because I did not have anything else.

The sound is really good but I did not think the wodden box had anything to do with it.

Note:
This project also relies on Rubys MCZ on all the +5v and a 1Farad combination after the +5v reg.

Special results....

Silver Micas are the best in the digital HF amp and Decoder.

After replacing 3 ceramics by SilverMicas, the sound became much more detailed and with attack.

Someone's player is filled with silver micas.... yes, it's good! I'd like some in mine at some point.

Get 'em in there Simon. I used to use polystyrene 1% and they sounded good. But 1% Silver Mica sound much better. They have a much smoother presentation, more natural, whereas poly's can be a bit bright.

Hi Simon,

I wouldn't even bother. Build yourself a headphone amp. Good fun and the results will be an awful lot better than anything you'll get out of the CD63.

I replaced the 78/7912's in my discrete stage for Raygulator's with zener's. It sounded better until one reg started to smoke.

Does the discrete pull too much current for the Raygulator? Or is it a faulty part?

Hi Pete,

Yeh, that's what I meant lol. I meant the CD63 feeding a nice headamp/pre.

Simon

ps - I'm ashamed to admit it but my Soundblaster X-Fi actually sounds quite good with my Sennheiser HD600s! Just as long as you don't turn on the w*nky "Crystaliser" or tell it you're using "headphones"!!!

I totally agree..... I am even considering replacing C505 with a silvermica... I will report on the differences (I believe there will be a good improvement)...

I am considering the rest of the mods in the output (C659 C660
R655 656 R657 / 658 R659 / 660) but would like to have your input in the two R619 R620..
As the CD53 does not have a HDAM, the entire circuit is replaced by a 10R in each channel.

Should I shunt these or should I wire the pin 7 of each opamp to R659 660 ?

If I am right, you remove everything in the output, leaving only the voltage drop circuit R659 / R661 and 660/662.

Removing R619 R620 will affect the values you indicate for voltage drop ?

Can anyone comment on this ?

I would like to try this modd but not sure of the possible outcome.
